Unveiling the Colours of Cellulose Nitrate Black and White Film-based Negatives in Colonial Photography

ABSTRACT

Aiming at contributing to the preservation of black and white (B&W) film-based negatives held by Portuguese archives, four photographic collections from the first half of the twentieth century were selected for study. During the macro assessment of the collections the preservation condition and hues found in photographic negatives from the Elmano Cunha e Costa (ECC) were noticed, distinguishing this collection from the remaining ones. Additional attention was given considering that the ECC collection was formed in a colonial context in the 1930s, while the others were formed on the Portugal mainland. The ECC collection results from an ethnographic survey of Angolan tribes recorded with B&W film-based negatives. In this collection, sets of negatives with pink, lemon yellow, greenish, orange brownish, and red brownish hues were found. To identify the origin of such hues, the image layer was analysed by microscale energy-dispersive X-ray fluorescence (μ EDXRF) and scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX). Additionally, to assess the base decay and its effect on the formation of hues, the plastic supports were characterized by Fourier transform infrared microscopy (μ FTIR). To complement the assessment of the film-base decay, pH was measured by using combined microelectrodes. The identification of mercury, iodine, chromium, and iron by μ EDXRF allowed correlation of the hues found in the negatives with chemical corrective treatments performed to improve the image quality. SEM-EDX confirmed those results and proved that the elements found were in the photographic emulsion layer. The results obtained are relevant since the hues identified may now be used as markers to indicate the technical work performed on colonial photography. Additionally, the visual and molecular assessment of the negatives’ supports (good to fair condition) allow proposing that the original storage conditions may have had a beneficial contribution to their present condition.     

关于当前高校摄影教学工作的实践与思考

随着读图时代的到来,引发了社会对摄影专业人才的呼唤和渴求,为培养适应素质优良的多元化摄影人才和部分从事摄影艺术创作的高素质人才,高校必须在原有传统摄影教学的基础上,改革摄影教学观念、教育方式、教学内容和教学方法,全面提高高校摄影教学质量,对大学生强化摄影实践技能及创新思维能力的培养,使之能够成为适应社会主义市场经济发展的高素质复合型人才。     

艺术对摄影的影响

从开始喜欢摄影到现在已经有两年多时间了,对摄影一直有一个比较模糊的认识,一直以为只是拿着相机,对着被拍摄物体接快门,很简单的一件事,慢慢的通过与许多专业人士的交往才发觉摄影原来不止是那么的简单,拍摄出来的作品好坏,与作品本身并无多大关系,关键的是作品有无内容,有无作者关于作品的感悟。     

Orphan Works at Theatre Library and Information Centres: Assessing Librarians' Perceptions and Management in Spain

Currently, libraries and other information services are facing new professional challenges in relation to digitization policies and orphan works after the publication of European Directive 2012/28/EU on certain permitted uses of orphan works and Spanish Royal Decree 224/2016. This paper aims to analyse how Spanish library and information centres specialising in theatre and performing arts meet users' textual and non-textual information needs, by respecting copyright issues and being involved in a dynamic and digital environment. For this purpose, an online questionnaire, which was used as a methodological tool, was sent to library directors in February 2018. At the same time, some research questions based on orphan works and digitisation approaches are discussed in the paper, specifically in reference to graphic and audiovisual materials.
